• Swedish eco-designers, Ehrnberg Solutions AB, have just completed their most successful prototype of the floating SeaTwirl vertical wind turbine. The device captures and harvests offshore wind, without having to convert the energy as it is being stored. SeaTwirl is the first of its kind with only two moving parts, and it uses only sea water as a roller bearing, omitting the need for a gearbox or transmission.

• A successful test installation has been carried out in the sea near Halmstad on the Swedish west coast. Intense weeks of building, launching and tests at sea have now been completed and the technology has proven to work excellent! Read more about the SeaTwirl prototype III.
  The development, construction and installation of the prototype is made in cooperation and with support of the following companies, organisations and institutions: Chalmers University of technology, Habasit AB, Ingeniörsfirman Myrén & Co. AB, Mekpart AB, Miltronic AB, Halmstad Hamn AB, Rexnord Industries, SP Technical Research Institute of Sweden, University of Gothenburg.

Pelamis Wave Power

Pelamis Wave Power Ltd is the manufacturer of a unique system to generate renewable electricity from ocean waves. Its first wave farm, located off the coast of Portugal, was opened in September of 2008.

clipped from en.wikipedia.org Pelamis Wave Energy Converter The Pelamis Wave Energy Converter is a technology that uses the motion of ocean surface waves to create electricity. The machine is made up of connected sections which flex and bend as waves pass, it is this motion which is used to generate electricity. Developed by the Scottish company Pelamis Wave Power (formally Ocean Power Delivery), it was the world’s first commercial scale machine to generate electricity into the grid from offshore wave energy and the first to be used in commercial wave farm project.[1] The first full scale prototype was successfully installed and generated electricity to the UK grid at the European Marine Energy Centre in Orkney, Scotland in August 2004.[2] The first wave farm, located off the coast of Portugal, was officially opened in September of 2008.[3] clipped from www.worldculturepictorial.com Pelamis in Portugal - world’s first, most ambitious, working wave farm, now generating electricity for 1,500 homes clipped from www.pelamiswave.com Pelamis Wave Power clipped from www.youtube.com

Green Hawaii

About a Hawaiian project to build a wave energy generator offshore in the ocean.

This is part of a partnership, intended to transform Hawaii into one of the world’s first economies based primarily on clean energy resources.

clipped from www.greenbang.com Hawaii ready to become green hub Hawaii has revealed its intention to move away from the setting of a popular 70s cop show and a surfers’ paradise to the setting for a clean energy rollout and green tech paradise. clipped from www.mauinews.com HONOLULU – An Australian company wants to build a 2.7-megawatt wave energy generator somewhere off the coast of Maui. Hawaiian Electric Co. had planned to wait to announce the idea until next month, when more details will be settled, but the news came out when a bill was introduced in the Legislature to authorize $20 million in tax-free development bonds. The generator gets its power from the rise and fall of the water, but the turbine is driven by air. A platform has an opening underwater. The surge of the ocean increases or decreases the pressure on air in a chamber. The air expands and contracts, driving the turbine blades.
